Unresponsive Script with Twitter

I've recently been having problems with some code on my blog, when I load it up in Firefox it now says "Warning: Unresponsive scripts ... http://platform.twitter.com/widgets.js:5". Any idea why this is happening all of a sudden?

I'm using Windows 7, Firefox 19.0. Thanks!
